The utility model is an aluminum electrolytic capacitor, which comprises a core, an aluminum shell, a foil guide and a cover plate, the core is put into the aluminum shell, and is sealed by the cover plate, wherein the foil guide and the cover When the plate is riveted, the method of punching and turning riveting is adopted. The aluminum electrolytic capacitor of the utility model is riveted by punching and riveting when the cover plate and the guide foil are riveted, and the contact resistance is well controlled at 0.3mΩ～0.4mΩ, forming a good contact characteristic and avoiding the early stage of the product caused by poor contact or open circuit failure, and better meet the reliability requirements of welding machines, UPS power supplies and frequency converters for the use of aluminum electrolytic capacitors.
Description
[technical field]
The utility model relates to a kind of aluminium electrolytic capacitor, relates in particular to the syndeton of leading chaff and cover plate is carried out improved aluminium electrolytic capacitor.
[background technology]
At present, what the connected mode of leading chaff and cover plate of big capacity aluminium electrolytic capacitor mainly adopted is the riveted joint mode, and it punches leading on the chaff specifically exactly, is enclosed within then on the rivet of cover plate to press together again.Owing to lead chaff and the cover plate rivet circumference has certain interval, lead chaff and the rivet contact area is very little, therefore, this kind riveted the riveted joint resistance of mode at 0.7m Ω～1m Ω.When contact resistance was bigger than normal, directly phenomenon was exactly that the electrical quantity loss is big, in the use, led chaff for a long time through big electric current, the heating oxidation of riveted joint contact site, and contact resistance continues to increase, and causes capacitor to lose efficacy.
, social demand amount increasingly mature along with device fabrication technology such as DC welder, frequency converter, ups powers also increases sharply; Its quality is had higher requirement; The quality requirement of the aluminium electrolytic capacitor that in these equipment, uses is also higher; Therefore, existing aluminium electrolytic capacitor is difficult to satisfy industrialized demand.
In view of above drawback, be necessary to provide a kind of improved aluminium electrolytic capacitor to overcome above-mentioned defective in fact.
[utility model content]
The purpose of the utility model is exactly that the spy provides a kind of aluminium electrolytic capacitor that reduces contact resistance in order to address the deficiencies of the prior art.
To achieve these goals, the utility model adopts following technical scheme: a kind of aluminium electrolytic capacitor, and it comprises fuse, aluminum hull, leads chaff and cover plate; Fuse is packed in the aluminum hull; And, wherein, describedly adopt punching to turn over the riveting riveted way when leading the riveted joint of chaff and cover plate by said cover plate for sealing.
Preferably, the said punching riveted holes that turns over riveting is the magic flower shape.
Preferably, described magic flower is shaped as rhombus.
Preferably, the described aluminium washer that is equipped with when leading the riveted joint of chaff and cover plate.
Compared with prior art; The utility model aluminium electrolytic capacitor uses punching to turn over the riveting riveted joint through cover plate with leading when chaff is riveted; Control contact resistance well at 0.3m Ω～0.4m Ω; Form the excellent contact characteristic, the product early failure of avoiding loose contact or open circuit to cause satisfies the instructions for use of these equipment of welding machine, ups power and frequency converter to the aluminium electrolytic capacitor reliability better.
[description of drawings]
Fig. 1 is the fuse schematic perspective view of the utility model aluminium electrolytic capacitor;
Fig. 2 is the riveted structure sketch map of leading chaff and cover plate of the utility model aluminium electrolytic capacitor.
[embodiment]
Please refer to Fig. 1, shown in 2, the utility model aluminium electrolytic capacitor, it comprises fuse 20, aluminum hull (not shown), leads chaff 14 and cover plate 21; Fuse 20 is packed in the aluminum hull; And by said cover plate 21 sealings, wherein, described leading when chaff 14 is riveted with cover plate 21 adopts punching to turn over the riveting riveted way.
The riveted holes 40 that riveting is turned in said punching is the magic flower shape, and in the utility model, described magic flower is shaped as rhombus.In order further to reduce the contact resistance of leading chaff 14 and cover plate 21, aforesaid leading also is equipped with aluminium washer 15 when chaff 14 is riveted with cover plate 21.
The utility model aluminium electrolytic capacitor; When riveting, chaff 14 use punching to turn over the riveting riveted joint with leading through cover plate 21; Fine control contact resistance is at 0.3～0.4m Ω; Form the excellent contact characteristic, the product early failure of avoiding loose contact or open circuit to cause better meets the requirement of these equipment of welding machine and frequency converter to product reliability.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
